A support ring 42 connected to the inner wall of thethird cavity 19 penetrates thering buckle 43 and the upper ends of the wedge blocks 41 are disposed at a gap with each other. The lower ends of the wedge blocks 41 are magnetized to be mutually attracted. Theclamping mechanism 4 is provided with a clamping throughhole 44 along the central axis. In an example, the lower end of the clamping throughhole 44 is chamfered to facilitate the penetration of the rivet into the clamping throughhole 44. In order to better clamp the rivet, the clamping throughhole 44 and the side structure of the rivet should be the same or similar. For example, a round rivet should operate with a round clamping throughhole 44. To rive the rivet deeper, the clamping throughhole 44 may be a stepped hole. - In an example of
FIG. 1 , thecontrol switch 23 is a push switch, and arubber cover 121 is disposed on theupper housing 12 to cover thecontrol switch 23. Control command is transmitted to thecontroller 21 by different tapping methods. For example, long press can switch the device on or off. Single clicking can make thesleeve 34 do a single tap, and double clicking makes thesleeve 34 continuously tap. - In an example of
FIG. 1 , thelower housing 13 is provided with a plurality ofhorizontal rulers 14 and/orvertical rulers 15 for stabilizing the housing and determining the riveting position. When thehorizontal ruler 14 is used, at least two mutually perpendicularhorizontal rulers 14 are used in combination, and of course, when thehorizontal ruler 14 is used, thevertical rule 15 can also be used in combination. - In an example of
FIG. 1 , the measuring surface of thehorizontal ruler 14 aligns with the bottom surface of thelower housing 13. The measuring surface of thevertical ruler 15 aligns with the vertical surface of thelower housing 13. The bottom surface of thelower housing 13 and the radial section of the housing may form a certain angle to be suitable for oblique riveting. Thehorizontal ruler 14 is indicated with scales, with the central axis of the clamping throughhole 44 being as the zero point. - In an example of
FIG. 1 , thecontrol mechanism 2 further includes aUSB connection port 24 for charging and data transmission. - In an example of
FIG. 1 , abearing 36 is fixed between thefirst cavity 16 and thesecond cavity 17, and thescrew 32 passes through thebearing 36 and is fixedly connected to the inner ring thereof. - In an example of
FIG. 1 , theslider 33 is provided with adistance sensor 37, and the detecting end of thedistance sensor 37 faces the inner wall of the upper end of thesecond cavity 17. Thedistance sensor 37 is used for thecontroller 21 to judge the position information at which theslider 33 is currently operated. Based on the position information, the motor can control the movement of theslider 33 by forward or reverse rotation. - In an example of
FIG. 3 , the bottom of thesleeve 34 is provided with arubber cushion 342. - The
controller 21 is electrically connected to thebattery 22, thecontrol switch 23, themotor 31, theUSB connection port 24, and thedistance sensor 37, respectively. Based on such connection, thedistance sensor 37 can obtain the position information on the movement of theslider 33, and thecontroller 21 controls the operation of the motor by pressing thecontrol switch 23. - The portable electromotive assistive device for rivet assembly of the present invention includes a housing, a control mechanism, a power mechanism and a clamping mechanism. A horizontal ruler and/or a vertical ruler are arranged on the housing to facilitate the determination of the riveting position. It also makes the rivet more easily riveted into the material to be fixed at a certain angle. The rivet is clamped in the housing by the clamping mechanism. The power mechanism taps the rivet under the control of the control mechanism. The rivet is parallel or coincident with the central axis of the sleeve of the power mechanism when the rivet is clamped, and the clamping force acting on the side of the rivet avoids the deformation caused by uneven force on the rivet. The device has a simple and reasonable structure, easy to use, high intelligent, safe and reliable, time and labor saving, and high practicability, etc. which effectively solves the problem of poor practicability of existing rivet assembly devices.
- The exemplary embodiments of the present invention are thus fully described. Although the description referred to particular embodiments; it will be clear to one skilled in the art that the present invention may be practiced with variations of these specific details. Hence this invention should not be construed as limited to the embodiments set forth herein.
